The CW teen drama boasts a mix of TV's hottest new faces and veteran stars, from KJ Apa and Cole Sprouse to Molly Ringwald and Skeet Ulrich. Here's where you've seen them before.

Can’t picture KJ Apa as anything but Riverdale’s Archie Andrews? Maybe it’s because you missed him in A Dog’s Purpose. On the flip side, maybe you have a hard time seeing Cole Sprouse as The CW series’ Jughead Jones because, to your TV-fan brain, he’s still awkward little Cody Martin from The Suite Life of Zack and Cody. Or Mädchen Amick – Betty’s mom Alice Cooper – is forever Twin Peaks’ Shelly Johnson.

Given that Riverdale has brought new faces and television veterans together for a wildly popular homage to the Archie comics and teen dramas alike, we wanted to take a look at where you saw the cast before they starred on The CW’s smash-hit — and what projects some of them have coming soon. Below, we take a look at some of Riverdale’s most shocking transformations.

But first, a reminder of what to expect in season 3: It’s been five months since we left the “town with pep,” and last we saw, Archie was arrested for murder after being framed by Hiram Lodge (Mark Consuelos). On the Southside, Jughead was crowned the “serpent king,” asked Betty (Lili Reinhart) to be his queen, and gave Cheryl (Madelaine Petsch) a signature red serpent jacket.

More trouble in paradise awaits Riverdale in season 3. Archie’s trial will bring his lawyer mom, Mary (Molly Ringwald), back to town to defend him, but District Attorney Ms. Wright (Penelope Ann Miller) won’t back down without a fight. Veronica will have a full plate with her boyfriend Archie in jail and Pop’s Chock’lit Shoppe to run. We will finally get to meet Jughead’s mother Gladys and his sister Jellybean. It looks like Betty’s family might join a cult — but with Hiram’s crime ring running amuck, who knows who the town’s next greatest threat will be. As far as special episodes go, the show’s creator, Roberto Aguirre-Sacasa ( “RAS” to fans), has promised a second musical episode and another set of meta-mini-sodes in the vein of last season’s “Tales from the Darkside.”

On top of all that, RAS has teased a highly anticipated flashback episode to when all the parents of Riverdale were in high school.
